As you have surely seen in the title of the subject, I have a small problem.
I currently own 2 images, of a doujinshi, for which I absolutely can not find, and the name of it, or the name of the author / artist ... Still on the theme of self-bondage , of course.

After much research on the internet (since 4 days I think), I'm starting to be exhausted to find anything. The pictures themselves are already rather nice to look at, but I would like to find the rest.

I have seen this picture before. I beleve that there were six pictures in the story, including the time shackle that the girl is using.
I'm sure I have the set somewhere on a cd or printed out on paper in a folder in a box in a ministorage somewhere.

It seems you can find the complete comic here: http://eromanga-daisuki.com/?p=22060
Sadly is in japanese, I don't know if they are showing the author, but I think it's the complete comic you were looking for.

O.o So there hat down! I thank you very much. I finally have the opportunity to see the continuation, and to download it no longer have to look for it.
In addition it frustrates me a little since I had searched on hitomi, but I had found nothing. Surely because I was not using the right "tag".
